To all whomvit may concern:

Be it known that I, FREDERICK PEITER, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented a certain new and useful Improvement' in Gas and Air`Controlling Means forv Coke-Ovens, of which the following is a full,clear, and exact description, reference being had to the accommethod orprocess' of coking coaljordinarily employed and I have alsodescribed mynovel f method4 whereby these objections are overcbme, said. processv'or -method consisting broadly in supplying to the combustion flues atthe beginning of the 'coking operation, va/n amount o'combustible gasand air sufiicient ste produce allofA the heat which can be safely andeiiicientl transmitted to the coal `mass to be cokedw ereby thepreheating of the -eoal and ktlie;ini'tial coking operation isateriallyexpedited, the supply of combussc ti lagases and`aif 'beinggradually reduced l as the coking operation continues until at theend'fof the coking period the amount is about the same, or slightly lessYthan has been heretofore. used during the whole operation, therebyavoiding the overheatin of the brick work during the latter part o thecoki-ng operation, Adecreasing the amount of cauliflower colte producedand producing a betterygrade of coke in ashorter space of The isothermalmethod oficoking coal r above described, and means for practisingIOVreVerSin/g the flow of air and waste gases through the checkers, itbeing arranged, as "it is,"solelyfor the purposeofcontrolling Ytheuantity lof" gasndair being delivered 4to 4means that Ihave devised thepresent opvtype of mechanism which may be employed be done. The vfirstmeans suggesting itself would be to open the reversing valve a lessamount each time, but as all of the ovens of a battery are controlled byone reversing mechanism and as some of them'would be nearlyv coked whileothers would be just .starting it would seem tounneeessarily complicatethe equipment and it is with the View of producing a simple and highlyefcient erative means.

It is the underlying principle of my in vention to control thetemperature in the lues so as to produce the best quality of coke fromavailable materials, and in the shortest time consistent therewith,regardless of whether this control shall be such :as to maintain vthemaximum temperaturefsafely l.attainable throughout the entire operation,`or such variation of this maximum 'asmay 7.5 be found most ,fdesirable.,I Iii-the drawings forming a part of this specification, yFigure 1 is/a sectional view partly in elevation of one end of a coke oven to whichmy improved operative means is connected; Fig.- 2 is a detailview partlyin. section of the gas valve and reversing mechanism; Figj is a planview ofthe same; Fig. 4 is a sectional View partly in elevation on theline 'l1-4 ofFig. 3; Fig'. 5 is an enlarged'sectional view of the dampercontrolling the air duct; and 6 is a plan View of the same.

Fig. 9 is an'end elevation of the structure illustrated in Fig. 7. i

In the general View `of Fig. 1 I have shown `but one end of an oven, andit will be understood that the opposite end of the oven iis equippedwith means substantially the same 10o as that shown in Fig. 1.

In practice I prefer to use a separate valve or throttling device in the.air and gas pipes or ducts Abetweentlfie reversing valveand 'the ovenburners and in carrying out thisv idea 105 I employ a shaft 10 mounted'in a bracket 11 vat a point adjacent the gas valves, and upon thisshaft is mounted the reversngjarm k12 adapted to alternately engage thestems 13 ofthe valves w14 controlling the inlet of gas 11o.

Thus We have thesupply of gas and air progressively and gradually reduced after theiirst period of iiring. The push rod 30 can be pulled out by handwhenever it is desired to open the duct 29. The cam 25 is constructedupon the same lines as the cam 2l so that the throttling of the air willbe in synchronism with the throttling ofthe fuel gas.

The apparatus herein shown and described is the preferred constructionfor accomplishing the operations herein set forth but 1t Wil beunderstood that certain changes and:Y modifications can be made Withoutdepart-? ing from the broad principle of the invention and within thescope of the appended claims.
